The lawsuit said Walls-Kaufman used a cane, crowbar or similar object to level a brain injury to Smith, who took his own life on 15 January. Jonathan Arden, DC’s former chief medical examiner, has attributed Smith’s death to post-concussion syndrome, which can lead to symptoms like depression and suicidal thoughts.
About a dozen people with the open-source intelligence group Deep State Dogs pored over evidence from the capitol attack for more than a month until they found footage of Smith and his assailants.
“We felt we had to do something to honor the memory and family of Officer Smith. It’s terrible that the bereaved were left in that situation,” Forrest Rogers from Deep State Dogs told HuffPost. “So we turned to the thing we do best: finding bad guys.”
Walls-Kaufman, a chiropractor, has said in the past that about 40% of his clients work at or around the Capitol. In January, he was quoted in a story about the riot, which implied he was in attendance.
